Libbie & George Custer evidently had a normal marriage. He wasn't the first man to cheat on his wife & won't be the last. Whatever went on between them they loved each other very much, how many other men would ride 200 miles in 2 days because he worried about his wife? He faced court martial for what he did. Libbie wrote about how they would close the door to his study & with only the light of the fireplace they would describe the house they wanted to build when he retired from the army, that sounds like my wife & I because we did the same thing.
Your comment shows exactly how you feel about Native American's. You sound like Indian women are beneath white american men & the word Squaw while it does mean woman in Eastern Woodland dialect it has become a racist term.
